With grate discharge mills – typically SAG, AG and ball mills – the conventional relining process at the discharge end usually involves removing the dischargers and grates, replacing with new lined versions and hammering in large, long bolts through the layers to …
How a Grate Discharge Ball Mill Works. Aug 13, 2015· How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are …
The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball …
Discharge arrangement Outotec provides a wide variety of discharge arrangements, such as overflow, peripheral, grate and open-ended. SAG and AG mills typically have grate discharge arrangements which can be either with or without trommel screens.
Outotec launched a grinding mill with an open-ended discharge, the OED Mill. This large high-capacity grinding mills offer reductions in both CAPEX and OPEX. Instead of using pulp lifters, the OED Mill discharges material directly through the grates. It uses a novel grate-supporting spider to maximize slurry transport and minimize slurry ...
We developed lifter, grate, pulp lifter and flow cavity through exit trommel model for the 40 ft Cadia mill in Australia. The study identified all wear zones, granular flow back into the mill and re-circulating flow inside the pan cavity for straight and curved lifters. At the time, we also modelled the water flow regime through the grate.
The company's new Open-Ended Discharge Grinding Mill (OED Mill) discharges material directly through the grates instead of using pulp lifters. This solves the throughput bottleneck problem associated with comminution …

A vibrating screen was used to provide a mill discharge product separation at 19 mm (¾ in.). The minus 76 trail (-3 in.) plus 19 mm (+¾ in.) screen oversize product, which are the "pebbles", were then crushed to essentially minus 19 mm (-¾ in.) in a crushing circuit. This product was returned to the feed end of the mill.
